She had a little trick up her chest: a big black heart shape marking. Incredibly, no one had noticed this anatomically correct heart patch before after that. Her humans fell in love with this adorable cat on the spot, and both black and white cat sis stayed united. As Zoë expanded, so did her heart and her hair. Her longer coat has gained her the label ‘The Fluff’, though she also goes by ‘Queen Of Hearts’.

Zoë and her sis Izzy have their own Instagram account, where they presently have nearly 75.000 followers. At first, most attention went to Zoë and her adorable heart-marking. But lately, the sisters have come to be equally popular as this adorable cat has actually amassed quite the fanbase of her very own due to her irresistible and expressive face.

The British Shorthair mixes are similarly adorable animals but have different personalities. Izzy is brave and adventurous, while Zoë is more careful, yet incredibly curious. Both unusual cats are very caring, towards their people and each other. Just take a look at these cute photos, and see if they can conquer your heart as well.
